Table 1:
Current range of ZE/XTOM motor overload relays
Temperature compensation
Two parameters influence the deflection of the bimetallic
releases. Firstly, the heat which is generated in proportion to
the current flow, and secondly, the ambient air temperature.
The influence of the ambient air temperature is automati-
cally compensated within a temperature range from -5 to
+50 °C by means of an additional current-free bimetallic
release that continuously corrects the tripping range.
Phase failure
ZE/XTOM overload relays are phase-failure sensitive.
The deflecting action of all three bimetallic releases is
directed towards a tripping bridge that switches over a
quick-break switch when the limit value is reached. At the
same time, all three bimetallic releases shift the differential
bridge.
